Self Care

See your doctor if the sore throat or fever lasts longer than 48 hours. He or she can do a test to find out if you have strep throat. If you do, your doctor may give you an antibiotic to treat it. You should also get plenty of rest, and drink lots of water. Gargling with warm salt water may help relieve a sore throat.
